MicroHTTPServer

A small HTTP server built from scratch in C#. The project uses TcpListener to demonstrate how HTTP requests can be read, parsed, and answered without ASP.NET or other web frameworks.

The server runs locally at http://127.0.0.1:13000 and includes small examples of routing, HTML pages, form handling, and file uploads.

Features

• Handles GET requests and selected POST requests
• Routes to a home page, about page, height form, and upload page
• Parses HTTP headers and request bodies manually
• Accepts multipart/form-data and saves uploaded files in uploads/
• Returns a simple 404 page for unknown routes

Getting started
